Hi, I am processing data from my DJI Matrice 350 RTK with an L2 payload used with an Emlid RS3 as a base. The data cover ~1km2 over mostly woodland flown at 50m altitude with tress ~23m. This was a total flight time of ~3 hours so there should be good coverage and line spacing. However, the resultant point cloud has consistant v-shaped artifacts throughout the data (see images). Can these be processed out?

Which overlaps did you use? And which settings during reconstruction?

Looks like not enough overlap between passes.
Why flying 50m AGL inside a forest with L2?? specially if trees are 25m height, of course you're too close to the trees. The overlap is calculated on ground.

For an environment like that, i use to fly a minimum of 85m, L2 data collection are pretty precise, you don't need to fly that low.

Yes, anytime you see artifacts like that that are exactly aligned with the flight lines and about halfway between them, it usually means not enough overlap, or improper calibration.

Like the others suggested, fly higher and increase overlap.
And no, it usually cannot be "processed out", without leaving gaps.
